Yes it can.

You'll need all those plus for best result, enable per-flow load balancing.

ihsan at cempaka> show configuration policy-options policy-statement
load-balance 
then {
    load-balance per-packet;
}

This policy is then applied under BGP peer and forwarding table export
policies.

ihsan at cempaka> show configuration protocols bgp group peer1 
type external;
multihop {
    ttl 3;
}
local-address 1.1.1.1;
import import-routes;
export [ export-routes load-balance ];
remove-private;
peer-as 1234;
neighbor 2.2.2.2;

ihsan at cempaka> show configuration routing-options forwarding-table 
export load-balance;

/ihsan

Hi,
   Which is the best way to get BGP load balancing up and running with the
same provider on a m7i using loopback IP? I've realised quite a number
enquiries on this matter on most forum. Can it be done? In cisco usually the
things needed are:

- 2 static routes pointing to the providers loopback IP
- ebgp multihop config
- update source loopback

Regards,
Kana
